Shop. Shop more. Shop hard. Walk away from it. Start shopping again. When you find a deal, know if it is a deal, a scam, rebuilt title, or something else. Confirm EVERY option you are looking for. Might say TRD, but is it truly a 4x4 if that is what you want? Stuff like that. Might be a CRV model listed as EX-L but if it doesn't have leather it isn't -L. Couple thousand difference in price.
When you find the one that checks all the boxes, be certain to offer money over the phone to hold it. If the deal is that good, it won't be there long.
In the Superduty I just bought, it was timing. Small dealer. Semi-retired. Was traveling for a month out of country. Emptying his inventory before he left. Listed everything at wholesale price. I just happened to find it the day he listed it.
And to be fair: this is NOT a perfect truck. It has some blemishes not many would notice.
@giles pointed out one when he saw it. I hadn't picked up on it nor had the guy with me or several others who had looked at it. It is also a plain model truck with some extras to dress it up. Amazing what a $1000 take off tire and rim package will do for appearance.
